Find LCM of 196,638,203,609,280 with Prime Factorization
2 | 196, 638, 203, 609, 280 |
2 | 98, 319, 203, 609, 140 |
7 | 49, 319, 203, 609, 70 |
29 | 7, 319, 29, 87, 10 |
7, 11, 1, 3, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 7 x 11 x 1 x 3 x 10 = 1875720
Therefore, the lowest common multiple of 196,638,203,609,280 is 1875720.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
196 x 638 x 203 x 609 x 280 = 4328606546880
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
638 : 1, 2, 11, 22, 29, 58, 319, 638
203 : 1, 7, 29, 203
609 : 1, 3, 7, 21, 29, 87, 203, 609
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,638,203,609,280, is 1.
Now, the common factors can be found like this.
196:2x 2x 7x 7
638:2x 11x 29
203:7x 29
609:3x 7x 29
280:2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 7x 7x 29x 29 = 2307704
Therefore, the value for common factors is 2307704.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 4328606546880/(1x2307704)
LCM = 4328606546880/2307704
LCM = 1875720
Thus, we can understand that the LCM of 196,638,203,609,280 is 1875720.
